United States Patent O DOOR STOP FITTINGS Bruno Oskar Svensson, UpplandsVasby, Sweden Application December 12, 1952, Serial No. 325,510

1 Claim. (Cl. 292-271) The present invention relates to a device forholding doors or the like open, and has for its object to provide adevice of this kind which is easy to mount and operate and is absolutelyreliable in use.

The device according to the invention comprises three very simple parts,namely, two fittings and one rod extending between said ttings andco-operating therewith, and its main feature is the special design ofthe fittings as well as the special way of functioning caused thereby.

An embodiment of the invention is described in the following text,reference being had therein to the accompanying drawing, in which Fig. 1is a perspective side view of the device as mounted for use, and

Fig. 2 is an end View of the same.

Referring now to the drawings, the numeral 1 designates a stopping ttingfastened to the bottom side of the upper, horizontal part of a doorframe 7. Said fitting 1 has an angular, downwardly projecting portion 9provided with a hole for receiving one end of a rod 4, and a likewisedownwardly projecting stopper 2. This stopper is spaced from the angularportion 9 and its edge nearest said angular portion is substantiallyvertical, while its remote edge is inclined downwardly towards theangular portion 9.

The numeral designates another fitting, which may be considered aslewing fitting, which is screwed fast to the upper part of a door 8.This tting is provided with an angular portion projecting horizontallyland having a hole receiving the other end of the rod 4. At this end,said rod 4 has an angular bend serving as a handle 6, which also givesthe rod a low centre of gravity. At the end thereof entering the hole inthe fitting 1, the rod 4 has a short angular bend 3. The diameter ofboth said holes are considerably larger than the diameter of the rod. Inthe drawing, which shows the device in the position it assumes when thedoor is open, said angularly formed portion 3 of the rod is projectingbetween the portion 9 ice and the stopper 2, abutting against the latterat any attempts to shut the door. To close the door, the handle 6 isswung somewhat away from the door 8 as indicated by dash lines in thedrawing, the angularly formed portion 3 of the rod passes the stopper 2and the rod glides through the hole in the portion 9 of the fitting 1.When the door is opened again, the portion 3 of the rod willautomatically slide over the inclined edge of the stopper 2, assume itschecked position between the stopper and the portion 9 and be kept inthis position on account of the low centre of gravity of the handle 6.

The two fittings may be fastened in diiierent places on the door frameand the door respectively, whereby the device is adjusted for holdingthe door open in various opening angles. Furthermore, the rod 4 is easyto remove to release the door completely.

I claim:

A door stop device comprising a stopping tting adapted to be fixed tothe lintel of a doorway, a slewing fitting adapted to be fixed to aportion of the door, each of said fittings having a guide means providedwith a hole extending therethrough, a retaining rod extending throughsaid holes in said guide means, said rod having both its end portionsextending at right angles, one to serve as a handle portion and theother as a stopping portion, said stopping iitting comprising a platehaving a rst portion provided with one of said holes and constitutingthe said guide means of said stopping fitting, said first portionprojecting at approximately right angles from said stopping tting plate,said plate also having a second portion spaced from said rst portion andforming a slot between itself and said rst portion, said retaining rodbeing rotatable by means of said handle portion through such an anglethat the stopping portion thereof can move out of said slot to let theretaining rod slide through said hole of the stopping tting during doorclosing movement, the handle portion serving as a weight to swing saidstopping portion into said slot at the end of the door opening movement,said hole of said stopping fitting having substantially the samediameter as said retaining rod thereby enabling the rod, during themovement of the stopping portion out of said slot, to rotate about anaxis which is identical with the axis of said retaining rod.
